DUNS ERROR 711
711 - RasMan initialization failure. Check the event log.
This error can occur with Windows NT 4.0 if the Plug and Play Service is disabled. This will also cause the inability to open Modems from Control Panel, and will prevent the detection of modem for Remote Access Service (RAS).
The error may also occur if a modem has been removed physically from a Windows NT 4.0 system, but not removed from RAS; or, if the modem has been replaced without adding the new modem to RAS. If this error occurs without removal or change to previously working modem, it may be possible that the modem has been damaged and can no longer operate.
To resolve this problem, make sure the Plug and Play service is running. Control Panel->Services. See this Microsoft KB Article.
If the modem has been removed from the machine and replaced with another, you need to add the new modem to RAS: My Computer->Dial Up Networking: Remove from the list of installed RAS modems any modem that is no longer present, and install (add) the new modem.
If the error persists, check that the modem driver has been properly installed. You can determine whether the modem works by using Hyperterminal connected directly to the modem's COM port (which does not require RAS). If the modem doesn't respond to AT commands in Hyperterminal, the modem driver may need to be removed and re-installed.
712 - Biplex port is initializing. Wait a few seconds and redial.
713 - No active ISDN lines are available.
714 - Not enough ISDN channels are available to make the call.
715 - Too many errors occurred because of poor phone line quality.
716 - The Remote Access IP configuration is unusable.
717 - No IP addresses are available in the static pool of Remote Access IP addresses.
DUNS ERROR 718
718 - PPP timeout.
This error indicates a PPP conversation was started, but was terminated because the remote server did not respond within an appropriate time. This can be caused by poor line quality or a problem with the server (ISP). This error can occur when your modem has connected to the ISP and has sent username and password, but there is no response from the server.
Sometimes, re-dialing will be successful.
This error can also occur if your ISP account has expired, or if the username or password you are using is invalid.
This error can occur if you have LCP extensions enabled in the TCP/IP Properties of the connectoid and your ISP does not support LCP extensions.
This error may also occur if you have one or more network cards in your machine, and the cards do not have TCP/IP protocol enabled, or if the TCP/IP settings are incorrect. (Go to Networking in Control Panel to examine the properties of your network adapters; or, if you are not using the network card(s), disable them in Control Panel->System->Hardware.)

DUNS ERROR 720
720 - No PPP control protocols configured.
All Operating Systems - This error can occur if you have not configured your Dial-up Networking settings to use a protocol supported by the ISP or system you are calling. Check the Server Types tab of your Dial-up connectoid. Most ISP's use TCP/IP protocol, and no others should be checked. There is a screenshot of a Windows 95 connectoid's Server Tab here. Also check the Dial-up Server selection. For most ISP's this will be PPP, although some may support SLIP or CSLIP.
If you have selected TCP/IP as the protocol, and it is not supported by the system you are calling, you may get this error. (For example, a Remote Access Server set up for NetBEUI.) Solution: Configure the Server Types of the DUNS connectoid to match the protocol installed on the remote server.
If you are connecting to a server that requires 128-bit encryption and your system doesn't have 128-bit encryption installed, you may get this error. This Microsoft page will detect and recommend 128-bit encryption upgrade. Also see: MS KB Article: Installing RRAS disables 128-bit encryption.
The installation of TCP/IP and/or dial-up networking may be damaged. Check ControlPanel->Network for TCP/IP assigned to (or bound to) the Dial-up Adapter. You can Remove, then Re-install the TCP/IP protocol (except with newer versions of Windows - see next paragraph). If you have a LAN card in your machine and access the Internet via a modem, unless you use TCP/IP on your LAN, TCP/IP should be assigned (bound) to only the Dial-up Adapter.
With Windows XP, you cannot re-install TCP/IP, but you can reset it with the following DOS command:
Click Start, then Run..., and put the following in the Open text box (or enter the following from a DOS command prompt which you can get by Start->Run-> cmd)
netsh int ip reset resetlog.txt
Windows NT: If you have configured RAS to only receive calls, you may receive this error. Go to the Remote Access Service tab on Services from ControlPanel->Network, and configure RAS for dial-out only, or dial-out and receive calls. See this MS KB Article.
Windows NT & 2000: This MS KB Article indicates the error (as well as error 611) may have several different causes, including the NETBIOS interface not being installed, or NETBIOS binding disabled.
DUNS ERROR 721
721 - Remote PPP peer is not responding.
This error may occur if there is a problem at the ISP. Disconnect, then dial back in. If error 721 persists:
· Try dialing into a different provider or access number if available
· Check the properties of, and/or create a new Connectoid
· Re-install dial-up networking (DUNS) - check Windows' networking properties.
· If you still have difficulty, enable and examine the PPP Log.
722 - The PPP packet is invalid.
723 - The phone number, including prefix and suffix, is too long.
724 - The IPX protocol cannot dial-out on the port because the computer is an IPX router.
725 The IPX protocol cannot dial-in on the port because the IPX router is not installed.
726 - The IPX protocol cannot be used for dial-out on more than one port at a time.
727 - Cannot access TCPCFG.DLL.
728 - Cannot find an IP adapter bound to Remote Access.
729 - SLIP cannot be used unless the IP protocol is installed.
730 - Computer registration is not complete.
731 - The protocol is not configured.
732 - The PPP negotiation is not converging.
DUNS ERROR 733
733 - The PPP control protocol for this network protocol is not available on the server.
All versions of Windows -
Installing Microsoft RRAS may disable 128-bit encryption. See this MS KB Article.
Windows NT & 2000 - TCP/IP protocol may not be correcting installed or bindings may be incorrect. See MS KB Article 168720.
Windows 2000 - This error may occur if the Negotiate multi-link option is enabled and you are dialing a normal one-call (single-link) connection. Solution: Start->Settings->Network & Dial-up Connections - right-click the connection, then Properties, Networking, Settings and clear the Negotiate multi-link for single link connections check box. See MSKB Article 244603.
Windows NT Server - See MSKB Article Q177648 and MSKB Article Q172956.

This Microsoft page will detect and recommend 128-bit encryption upgrade.
DUNS ERROR 735
735 - The requested address was rejected by the server.
All versions of Windows: Make sure your connectoid settings are correct - in particular make sure that network (TCP/IP) settings are to obtain an IP address automatically (do not specify an IP address); and, that WINS is disabled.
Windows 2000 & XP: This error may occur when a connection is (re-)established without successfully (re-)negotiating a network protocol. This is a known problem with Windows 2000 & XP - Microsoft has a fix. With Windows 2000, the problem was first corrected with Service Pack 4. A Windows XP fix should be included starting with Service Pack 2, or a separate interim patch is available from Microsoft. See: MS KB 812401
DUNS ERROR 736
736 - The remote computer terminated the control protocol.
This error may occur if the remote access server is unable to obtain an IP address (via DHCP) for the connection.
User report indicates this has occurred with Shiva Lanrover E Plus (now an Intel product), and the problem was solved by configuring the Shiva to act as DHCP server.
